Application flled.Septemb er 11, 1911. Serial No. 648,812.

To all whom it may concern: Be it known that I, ARTHUR L. OLSSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles andautomatically winding up the reel to coil the hose thereon after use.

By this invention, the nozzle end of the hose may be carried forward 'to the point where it is desired to water, and the reel will unwind to permit of this. The water may be turned on and the hose used at that point, orwhile the water is still flowing, the hose may be carried farther away to other points, or it may be carried back to-- ward the reel, the reelautomatically rewinding the hose, all of these operations being performed without interrupting the flow of the water.

Referringto the drawings: Figure 1 is a side elevation of the invention showing it in place below the floor of a house, the side wall of the house being in section. Fig. 2 is a section on an enlarged, scale on line w m Fig. 1. Fig. 3 is a section on line oa -m Fig. 2.. Fig.4 is a detail view in side elevation of the ratchet and its controlling mechanism, the view being contracted in length. Fig. 5 is a section on line w m Fig. 4. v i

1 designates the reel, which consists of a frame work with transverse bars 2 and longitudinal bars 3, the transverse bars 2 servlng as supports f or the longitudinal bars 3, the latter acting to support the hose 4. The

transverse bars 2 are mounted on a hollow shaft 5, which consists of a pipe as shown. One end of. the hollow shaft 5 is journaled in a bearing 6 as shown in Fig. 2, its other, end being journaled in a bearing 7 the bearings 6 and 7 being supported b suitable brackets 8. At one end of the ollow shaft-5 is a swivel coupling 9 which connects with the stationary water supply pipe 10, the latter being shown in Fi 1 as a branch and leading from the regu ar house. pipe 11, it bemg preferred to attach the branch 10 to the plpe 11 outside of the wall of the house as shown, and'to provide a valve 12 by means of which the water can readily be admitted to the pipe 10 and thence to the hollow shaft 5 from the outside of the house.

designates the regular outside valve to whlch the hose may be attached when desired in the ordinary manner.

' The hollow shaft 5 has a cross coupling 14 to which are connected radial pipes 15 and16, the latter having acap 17 on its end to close it, while the plpe 15 has an .elbow 16, as most clearly shown in Fig. 3, to which the hose 4 is connected by any ordinary hose coupling 17.- .Thus the hose 4 is always in ,communlcatlon with the hollow shaft 5, and,

through the latter, with the branch pipe 10.

A rewinding reel 18 is .arranged on the hollow shaft 5 as shown in Fi .2, and wound thereon is a flexible connect-1on19, which,

as shown in Fig. 1, is connected 'to a spring 20, and is so arranged that when the hose .is unwound from the reel 1 the connection 1 9 Wlll be .wound upon the rewinding reel 18 and place the sprlng 20 under tension so that if there 1s no opposition to the rewinding ofthe reel 1, the spring 20v will pull upon the connection 19, and the latter, actmg through rewinding reel 18 and hollow shaft 5, will turn the reel 1 in a direction to rewind the hose thereon. The rewindmg actlon of the reel is normally automatically prevented by means of a ratchet wheel 21, which is engaged by a pawl 22.

As clearly shown in F1gs. 1 and 4, the pawl 22 is connected by a link 23 with a lever 24 which is pivotally suspended by a spring 25 and has an inclined end 26 which is engaged b a pivoted arm 27, the latter being operate by a pull rod 28 which extends outside the wall of the house, as shown in Fig. 1. The pawl 22- normally engages the ratchet wheel 21 and prevents the rewinding movement of, the reel 1, and thus when the hose is unreeled and is being used, there is no backward pull on the hose which would make it diflicult to properly work with the hose. When, however, it is desired to rewind the hose the pull rod 28 is pulled outward, which-causes the lever 27 to act against the inclined portion 26 of lever '24 and tilt the latter, thereby lifting the pawl.

22 and disengaging. the ratchetwheel 21,

all of these operations may be performed while the water is flowingithrough the hose. There is no occasion for' connecting or dis-, connecting the hose from the reel 1 and the trouble of carrying the hose to and from the hydrant or connection is eliminated, and,

besides saving much time and annoyance, the hose itself is kept in perfect condition, as it is properly wound on the reel at all times when itis not in use, this being accomplished without any manual effort other than that required to operate the pull rod 28. What I claim is:

1. The combination of a supply pipe, fixed supporting brackets, a hollow shaft mounted in the brackets, having a rewinding reel, a swivel coupling connected with the supply pipe and a radlal pipe provided with a hose connection, a hose frame fixed to the hollow shaft, means for locking the hollow shaft from winding movement, means for releasing the locking means, a fixed tension spring, and a flexible connection wound around the rewinding reel and having its outer end connected with the outer end of the tension spring.

2. The combination of a supply pipe, fixed supporting brackets, a hollow shaft mounted in the brackets having a swivel coupling connected withthe supply pipe and a radial pipe provided with a hose connection, a hose frame fixed to the hollow shaft, a ratchet-wheel fixed to the hollow shaft, a

suspended lever, having an inclined outer end, a pawl engaging the ratchet-wheel, a

link connecting the inner end of the lever with the pawl, a pivotal arm engaging the inclined outer end of the lever, and a pull rod secured to the pivoted arm.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 5th day of September, 1911.
